Samplenotifier

Samplenotifier is a software component or library designed to monitor streams of numerical samples and emit notifications when predefined conditions are met. It is commonly used in signal processing, data monitoring, and event-driven architectures to decouple sampling logic from action handling.

Key features include an event-driven interface, support for configurable trigger conditions (such as sample value thresholds, value changes, rate of change, or pattern matches), and multiple output options (callbacks, message buses, or webhooks). Most implementations provide debouncing or rate-limiting to prevent notification floods and allow aggregation over time windows. The component is typically designed to be independent of the data source and can handle high-throughput streams while maintaining low latency.

Architecture usually comprises input adapters that ingest samples, a rule engine or detector that evaluates configured criteria, and an output router or dispatcher that delivers events to registered handlers. Some designs include a persistent store for event history, pluggable backends for telemetry, and a simple configuration API for setting thresholds, time windows, and debounce settings.

Common use cases include peak or clip detection in audio processing, threshold-based alerts in IoT and sensor networks, and anomaly detection in telemetry streams. In software testing, samplenotifier-style components can trigger test actions when specific sample patterns occur.

Note that samplenotifier is not a standardized, widely defined term; implementations and APIs vary across projects. The name may describe any component with similar responsibilities in different ecosystems, and some projects may offer extended features such as statistical detection, backoff strategies, or complex event processing.
